Expo CLI

Expo CLI is a command line app that is the main interface between a developer and Expo tools. You'll use it for a variety of tasks, such as:

Creating new projects
Developing your app: running the project server, viewing logs, opening your app in a simulator
Publishing your app JavaScript and other assets and managing releasing them as updates
Building binaries (aab and ipa files) to be uploaded to the App Store and Play Store
Managing Apple Credentials and Google Keystores

You may use the CLI in your terminal or use the web based interface (it opens automatically by default, or you can press d from the CLI to open it on demand). The web interface enables you to use some of the most often used features from a quick-to-use graphical interface. We’ve only scratched the surface of what expo-cli can do so far. Be sure to check out all the possible commands below!

Installation

Terminal

→ npm install -g expo-cli

Checking CLI Version

Run expo --version to determine what version you are currently working with.

Commands

The commands listed below are derived from the latest version of Expo CLI. You can view the list of commands available with your version in your terminal using expo --help. To learn more about a specific command and its options use expo [command] --help.
